The TU2000 is an ultrasonic level transmitter designed to measure distance, level or volume without physical contact with the measured product. Using the ToF (Time of Flight) principle with ultrasonic pulses, the device performs measurements of up to 20 meters in liquids, solids and grains, in both static and moving media. Its Bluetooth configuration through the SigNow app makes it a versatile solution for different types of tanks, including those with irregular shapes.

Why Choose the TU2000 for Level Measurement?

Reliable measurements in industrial processes are essential for operational safety and efficiency. The TU2000 eliminates the drawbacks of traditional sensors that require direct contact with the material, which wears down the equipment and shortens its service life. Because it depends neither on physical contact nor on light to measure, it is not affected by smoke, color or optical reflectivity of the surface, keeping readings reliable even with agitation or turbulence. In addition, the built-in temperature compensation, with a sensor located on the surface of the sensing element itself, ensures consistent accuracy in environments with temperature variations.

• Accuracy: min. 30 mm, max. 2 mm

• Operating temperature: -20 to 80 °C

• Degree of protection: IP67

Applications:

• Grain and solids silos

• Industrial tanks of various shapes (cylindrical, vertical, horizontal or irregular)

• Water treatment plants

• Level monitoring of rivers and dams

Advantages of a Non-Intrusive Sensor

In industrial processes, it is essential to have measuring equipment that ensures reliability and durability, regardless of environmental conditions. By having no direct contact with the materials, the TU2000 avoids the corrosion and damage that typically affect traditional sensors. Moreover, its simplified Bluetooth configuration through the SigNow software, with a guided wizard and echo graph for diagnostics, makes commissioning and maintenance of the equipment easier.

The TU2000 is ideal for industries that handle moving liquids, agitated surfaces or hard-to-handle solids. Its ultrasonic technology delivers stable measurements under challenging conditions, without the need for frequent equipment replacement due to contact wear. Since it adapts to liquids, solids and grains, it is a versatile option for tanks and silos that store various products at different stages of the process.
